..in this case I didn't use hal, I'm just a beginner, but since I didn't know anything, this is great. As for the configuration in this case, it's all down to the poor Chinese manual for the ASSD driver of the servo motor, the basis is that at the beginning I thought it could only work in 3 modes position/speed/torque.. I listened to your old advice to rest for a day , the next night I read the instructions from beginning to end..every parameter..in the end I realized that the driver has the possibility to change the mode of operation through the input..it is possible to switch from position to speed, but there is one more thing..it inputs in the driver are already factory set to default. they have to be allocated.. (if someone needs parameters I will be happy to help also will attach all hal/ini)... then I connected the output from the Mesa 7i96s to a relay that changes the operating mode on the driver from A (step dir) to S (speed ) .In the gcode, it is only necessary to enter M64 P0 for example and the output activates the input on the driver, change the operating mode and after the m64 command, put M3... follows the S command. Considering that I have no need for accurate indexing, this one has exactly what I wanted for me. Thanks Tom, I'll probably need help in the future with connecting the MPG.. when I get it all done with axis... than Mpg in the end.. beer is always ready if you're up to it Nis get in touch-;))/Hvala

Today I have an idea that I might implement, but I need some advice. the plan is to install an encoder on the knife holder so that with scaling it can read a full 360 degree circle. I would make a reference knife that would be 0 degrees to z or x axis, and in order to manually rotate the holder, a vcp should be made on the screen, that would show the dro encoder reading, referenced to that zero. is it possible to do that, since the spindle encoder input is not needed on the 7i96s would I use it? thanks for the support again with how to configure Hal.

..this would help me in practice, to be able to position the knife relative to the workpiece, at a certain angle.

jogging  youtube.com/shorts/ObnzluSeB4Q?feature=share
  MDI  youtube.com/shorts/PqXwrarzofU


today I installed the longitudinal axis, I have a problem, in long press jogging mode the machine skips, jumping (see screwdriver) no matter what the feed is, in MDI mode for example g1 z200 f1500 works smooth. I tried changing the acceleration, from 100-1000, at 100 (joint following error) between 100-1000 there is no error, but there is no difference either. Anyone with an idea what it could be?

That is a keyboard issue,
